摘要
摘要: 以浙江省天台山七子花群落为对象, 分析了七子花群落的植物区系组成和高等植物物种多样性。据9个样地统计, 共有维管植物69科、143属、186种(含变种)。从种子植物属的地理成分来看, 温带分布的类型居多。在群落垂直结构中, 乔木层第2亚层的物种丰富度、物种多样性指数均显著大于第1亚层, 它们之间的均匀度差异不显著。乔木层与灌木层之间多样性各项指标均无显著差别。乔木层、灌木层的物种丰富度、物种多样性指数均明显大于草本层。七子花群落科、属、种组成多样性高, 群落植物种类丰富, 组成复杂。
Abstract: The floral composition and the higher plant species diversity of the Heptacodium miconioides community in the Tiantai Mountain of Zhejiang Province were analyzed.According to the statistics of nine plots, there are altogether69families of seed plants(including varieties) which can be subdivided into 186species, 143genus.Most of them are distributed in the temperate zone in terms of the geographic composition of seed plant genera.In the vertical structure of community, both the species richness and species diversity index of the second sublayer of tree layer are much greater than those of the first sublayer, and their evenness is of slight different significance.The various indexes of diversity between the tree layer and the shrub layer have slight differences.The species richness and species diversity index of the tree layer and shrub layer are obviously bigger than those of the herb layer.The Heptacodium miconioides community has a high composition diversity of species, genus and family, the community has a great variety of plants whose composition is complex.
